Network & Server Tools

Free network tools — an Nginx config generator and an IPv4/IPv6 subnet calculator with VLSM planning and reverse DNS. Both run in your browser.

For planning before touching production: generate an Nginx server block with modern TLS and rate limiting to compare against your own, or slice an IPv4/IPv6 range into subnets with VLSM before committing it to router config. Both run locally in your browser.
